Bonjour
Voici la réponse d'Adobe : We are sorry about the issues you are facing while trying to import images to Lightroom Classic from your SD card or your hard drive.
Would you mind checking if the images are visible in finder on your Mac? Also, we have released a new version for Lightroom Classic (version 9.0) to which you can update the application through the Creative Cloud.
La version 9.0 n'est pas encore disponible, dans mon espace, du moins .
Merci encore, et bonne journée.
